There are really two BCRXs.
1. BCRX the company. History of failure, dubious management, a drug, peramivir that failed phase 111 followed by JNJ exiting.
2. BCRX the stock.
Like all mania, MO-MOs stocks, the two can be totally disconnected for long periods of time. Reality always wins in the end but the end can be a long ways off.
We've all seen them. TASR, ENRON, NVEC, KKD, CAFE, CGMI, Pets.com, GNTA, HGSI, ABGX. A never ending and ever changing parade of tulips. A few turn out to be the real thing, many others go back where they came from.
The thing to do is make hay while the sun shines. And try not be a bagholder aka The Greatest Fool.
